If your roofing budget has room for extras raised ridge caps will surely add to the aesthetics of your roof. These caps give your roof edges an additional 3-dimensional look which greatly increases the curb-side appeal of a home. They can be purchased to match any colour or style of shingle.

Zinc strips are an effective means by which to fight the growth of moss on a roof. They are a preventative means, which insiuates that the strips should be put on whenever moss growth is expected (when there are trees overhanging a roof which does not receive much direct light, for example). The strip is installed between two layers of shingles near the top of a roof, hence a silver strip approximately 2" wide will be visible near the ridge.
If, however, you choose to have zinc strips installed in the future, they are quite easy to install and can therefore be delayed.
